Need help with binding. tags for composite.xml files

I am getting some errors when trying to deploy some apps to a jar file.

In particular, I am not sure when to use .endpoint and .interface in the port attribute of <binding.ws>:

Also not sure exactly how to decide on what goes in the parentheses. I know it is something like (service name/port name), but I am un sure if I need full url's, or if there is somewhere in the project that can help me decide what to put in there. That kind of thing. Any kind of direction or url to a tutorial or two would be great.

There are a few different cases, so I will put two or three here in hopes I can get some guidance on them. The only areas giving me issues are the binding.ws tags, the rest I am fine with.

Thanks

(the two examples below only have one spot each where I am not sure, and the third example has two - I tried to mark them to make themobvious with <---- but they still might be hard to spot somewhat
